Museum overbooked? The Bronx Zoo too much of a hassle? Take the kids to the grocery store.

Under a new arrangement with more than 30 city public elementary schools, local Waldbaum’s supermarkets will be the latest field-trip destination for hundreds of young students this fall.

Cash-strapped schools have in the past taken schoolkids to city retail stores such as Petco and Sports Authority – where they can cuddle small animals and jump rope.

But the 90-minute grocery-store trips are designed to reinforce the schools’ curriculum on nutrition and teach children to “comparison shop.”

Students are offered samples of exotic fruits and vegetables that they might not get at home, such as kiwi or papaya, and leave their supermarket tour with a goodie bag containing health food and nutritional information.

Susan Singer, president of the Chicago-based Field Trip Factory that coordinates the trips, said the excursions help children make healthy decisions.

“We feel the lessons in the grocery store are the most valuable life lessons that can be taught,” Singer said.
